Butter Beer is a favourite drink served at pubs frequented by Witches and Wizards. For example the Three Broomsticks in Hogsmeade and the Leaky Cauldron in Diagon Alley both serve Butter Beer. It can be served hot and foamy or chilled. Madam Rosmerta, the proprietor of The Three Broomsticks Inn is known to serve up excellent Butter Beer.
